This document provides instructions for setting up a Raspberry Pi as a CCTV client that streams video to a Windows PC over a network using netcat. It outlines the necessary hardware of a Raspberry Pi, Pi camera module, and Windows PC. It then gives step-by-step directions for configuring the Raspberry Pi camera with Raspbian and raspivid, setting up netcat on the Windows PC, and running commands to stream and view the video feed from the Pi camera on the PC in real-time. Additional tips are provided for improving network speed and adding sound or multiple cameras.
Raspberry pi jam july
- 1. RASPBERRY PI JAM Setup Raspberry Pi as CCTV client
- 2. Who am I? • Name : Jon Ho • Occupation : Simcard OneXOX seller – Buy my prepaid card and top up RM 50, and you get 2 years validity, FOR FREEEEEEE! • Part Time : Freelancer/Maker • Some Time : Busker/Farmer/Fisherman
- 4. RECIPE • Hardware – 1 Command & Control Windows PC – Nth number of client Pi Camera • Software – Raspbian Jessie on Raspberry Pi – Raspivid www.raspberrypi.org/documentation/raspbian/applications/camera.md – Zenmap, Mplayer on Windows PC
- 5. Linux Streaming • VLC – Slowest – Easiest to set up • Gstreamer – So-so speed – Complex to set up • Netcat – Fastest! – No setup needed! Runs out of the box!

- 7. What you need • 1: Raspberry Pi 3
- 8. What you need (cont) • 2: Pi Camera Module (Noir)
- 9. What you need (cont) • 3: PC/Laptop Windows with zenmap/ncat (for network streaming stuff) and mplayer (for video stuff) installed – Both are opensource and freeeeee
- 10. Step 1: setup the C&C • First, find out your C&C PC’s ip – Open a terminal in windows and run ipconfig – Remember the ip, this is what your raspi will connect to
- 11. Step 1: setup the C&C (Cont) • Second, in the same terminal, run ncat to pipe the stream to mplayer – C:Usersjon>ncat -l -p 2222 | "C:Program Files (x86)MPlayer for Windowsmplayer.exe" -fps 200 -demuxer h264es – – The -demuxer h264es arguments decode the stream into mpeg 4
- 12. Step 2: setup the pi camera • Setup Camera – There are tons of tutorials of how to setup pi camera, so I will not cover that. Just make sure it looks something like below. – Also if possible, try to get an enclosure for the raspi camera. You don’t want it to die every time somebody sneezes at it
- 13. Step 2: setup the pi camera (cont) • Test Camera by running this command in the terminal – raspivid -o heuheuheu.h264 -t 10000 – omxplayer heuheuheu.h264
- 14. Step 3: profit! • Now put it all together by running this command on the raspi camera – raspivid -t 0 -w 1280 -h 720 -hf -ih -fps 20 -o - | nc 192.168.1.4 -k -l -p 2222 The –t 0 argument means raspivid will basically run forever streamed on port 2222
- 15. It’s alive! • It’s working!
- 16. Bonus Points • SOUND – The demo had no sound, due to lack of usb mic. It can stream sound. Try it out as homework. • NETWORK SPEED – For best live action speed, use a wireless router that can transmit on the 5GHz band. 2000++ Mbps means no lag whatsoever!
- 17. Bonus Points (cont) • MULTIPLEXING CAMERA – It is possible to multiplex the camera, although stability issue may arise.
